Gloating that he goaded People for the Ethical Treatment of Animals into making a flash-game free advertisement for indie hit Super Meat Boy, the game's co-creator followed up with an unlockable Super Tofu Boy character for the game's PC version.

The game hit Steam just yesterday, so, that's fast turnaround by Team Meat. A tweet this afternoon says the character is unlocked by typing in petaphile at the character select screen.

Edmund McMillan, the game's co-creator, says he "repeatedly made fake user names in Peta's forum pushing the game at them in hopes something like this would happen."

"Peta is 1,000 times more well known than Super Meat Boy and the fact that they went out of their way to make a parody like this is beyond flattering and amazingly helpful," McMillan writes.

McMillan notes that he himself was once a vegetarian and has worked as an animal control officer. He disagrees with Peta's absolutist stance against laboratory testing of animals, saying that has led to medical discoveries and treatments that save lives - like that of his mother, who is diabetic.
